[Linux-cluster] postgres cluster without shared storage



Hi all, 

I need to mount a two nodes cluster with postgres as service. I have mounted it in the past but with a shared storage and using GFS but now I don´t have this element. 

The idea is to have a master node with all the data in its own disk and have a mechanism to replicate this data to the slave node in its own disk. If the master goes down the slave begin to give the service and the flow of data will go from this node to the other one. (the slave node becomes the master one)

Is it possible to do something like this?

Thanks in advance, 

ESG
